wrench87 The nascar crank has wider bearing for the rods than stock one's. The Rods and crank are heavier also. If you are looking for a crank,rod and piston kit, balanced. Try Barry R. here or FE forum. He is also on e-bay. It's a drop in kit. Al you need is the spec on the block. Compression you want. 1-4 week wait depending on the kit. He has some in stock.
